Letters Patent No. 98,6571, dated January d, 187() MPRQVEIVIENT IN APPARATUS FOR TANING- HIDES .AND SKINS.

` The Schedule referred to in these Letters Patent and making part of the same.

To all whom 'it may concern: l

Be it known that we, WILLIAM Y.- WARNER and JAMES CnooKs, of the city of Wilmington, in the county of New Castle, andSt-ate of Delaware, have invented a new and improved Apparatus for Tanning Skins and Hides; -and we do hereby declare that the following isafnll, clean-and exact description of the construction and operation of the same, reference being hadto the annexed drawings, making a part of this specification, in whiche- Figure 4l is a front vie-w of a machine embodying our invention Figure 2, an end view;

Figure 3, a longitudinal section;

vFigure 4, a sectionV of the valve in the hose;

Figure 5, a vertical transverse section, showing the end of the machine, which is at the right hand in iig. 1; and

Figure 6 is a section through the centre of the gauge-box and its slides.

- Nature and Object of the Invention.

The first part of our invention consists in 'the combination of a feeding-trough containing tanning-liquor, filling-hose with funnel-connections and valved ends, a gauge-box with slides for feeding tanning-materials into the skins or hides, operated by means of rod and spring, having attached to it a tapering pipe, which receives the tanning-materialrin its passage into th skins or hides, and a smaller pipe, which'leads the water from the Yliquor-feeding trough into this tapering pipe.

The object of this part of our invention is to obviate the necessity of` using a funnel and .dpper in the filling of the skins with tanning-materialand liquor, and to enable the workman to fill both, at the same time, without waste.

The second part of our invention consists of a valve, which'is applied tothe mouth or opening of the skin or hide which retains the liquor, when distended or lled.

The object of this second part of our invention is to dispense with the troublesome process of tying and untying the mouths or necksof the skin, in filling, and, at the same time, retain the tanning-material.

General Description.

i before set forth.

G is the pipe which carries the tanning-liquor from the feedingtrough A into the tapering pipe F, for the -purpose of forcing the tanning-material into the skins orjhides.

-H is the valve, which is fastened to the mouth of each skin or hide.

I is the bin for holding the sumac, or tanning-material.

K isV the tan-tub, in which the skins are filled, and from which the liquor is pumped back in the feedingtrough A, when required. v

The skins to be tanned, after sewing, h/ave the valve H attached. The liquor is pumped from the tan-tub K into the trough A, which runs the whole length of the tan-tub.

The sumac, or other tanning-material, is fed fromY slides S S, in the gauge-box E, are pulled forward, the

tanning-material descends, the valves S S closing instantly, while the liquor, which is constantly running through the small pipe G, washes all into the skin, which is then removed, and passed to the workman stationed in charge of the filling-hose B, who brings the mouth of the skin under the valved end of the hose, which forces up the valve D, and the skin is entirely tilled. Here, the operation is compiete, andthe skins or hides remain in the tan-tub until it becomes necessary to rell them.

We claim, as our inventionv l. The feeding-trough A, in combination with the series of pipes B, B, F, and G, substantially as and for the purposes set forth. i

2. The hose B, with its funnel-head O and valve D, when used for like.purposes, substantially as set forth.

3. The gauge-box E, with its slides S S, operating substantially as described, for the purposes mentioned.

4. The gauge-box E, with its slides S S, in combination with the tapering pipe F and connecting-pipe G, and bin I, substantially as and for the purposes herenbefore specied.

5. The 'valved mouth-piece H, substantially as and for the purposes herei'nbeiore described.

6. The combination of the following elements or parts: the feeding-trough A, the filling-'hose B with its funnel C and valve D attached, the bin ll, the gangebox E with its slides S S, the tapering pipe F and its connecting-pipe G, and the valve H, substantially as hereinbefore described, as and for the purposes herein- W. Y. WARNER.
